Yes: I really like the size markings on it so that I can roll out the right sheet of fondant to cover a cake. I find it easier to trim the sheet and use just the right amount so as not to have to move an unnecessarily huge piece.

No: I have another mat which is non-slip on the underside, but alas no size markings on it. The Wilton one isn't so it slides around the benchtop more.

having used the roll and cut mat, i find it a really useful item. if , like me, you are a beginner then you will find all the measurements easy to use. much easier than getting out your tape measure each time to check sizing etc!! I personally wouldn't be without it now, to me it was money well spent!
